It is important to always update any software. This includes Burd IRC of course! It is very very very simple to update the Burd IRC client. Not to mention you get all the new features new versions sometimes include.

Once Burd IRC is open if there is an new update a pop message will appear once Burd IRC is open.
It will say there is an new update is available. It will have the option to update now or cancel and update later.
